Ascendo DSP4 1500 Watt Amplifier

This is where pro power meets residential refinement. Engineered for real-world low-frequency duty, this DSP amplifier delivers what conventional residential amplifiers and typical pro amplifiers rarely combine: sustained output down to 5–10Hz, 6600W RMS capability, low-noise cooling quiet enough for living-room use, and smart integration features such as selectable 12V trigger input logic, trigger out, configurable auto-standby, and Ethernet-based multi-amplifier control. 

High-Power Subwoofer Amplifier For Demanding Bass Systems

Stable at 2 Ohms and bridgeable into 4 Ohm loads, it is built to command even the largest and most demanding subwoofer systems with confidence, control, and staying power. Whether used as a standalone flagship amplifier or integrated into a clean 19-inch rack, it delivers the rare combination of brute force, sophistication, and everyday usability that high-end residential systems demand.
